HOW TO: Outside shore power monitor for winter storage

John E Davies

Recommended Posts



My trailer is stored inside and secure, but the power cord is hidden out of sight on the far side. Some power cords have a little LED to tell you they are powered. Mine did not, and the adapter that screws into the shore power receptacle failed internally, with no visible signs of distress... I had no clue that there was no power coming into the trailer. I went inside and found the 110v outlets and microwave dead and the converter not charging.


I had made up a tester for campground power, so I just plugged it into the street side outlet and angled the Y adapter forward so I can see it every time I go into the garage,


Here are the parts:






For only $15 you can have a very obvious display to make sure your batteries don't discharge. If you count on an electric heater to keep stuff warm, this lets you know that it still has juice. If you store in inclement weather this will not be safe. I added the surveyor's flagging to keep somebody from bumping into the open outlet cover.


In the dark the little blue display glows like a night light, telling you All Is Well.




I think it would be very cool to have a teeny LED mounted in the exterior wall near the entry door that would glow any time the 110 VAC was powered up. That would be straight forward and quite cheap, and a great solution for those who keep their Ollies out in the rain and snow, or for those who camp in winter and reply on shore power. Wire one of these $2 lights to the microwave outlet box, and make sure the microwave breaker is always closed so it stays powered. ... https://www.amazon.com/Blue-Sea-Systems-120V-Green/dp/B000K2IKPK?ref_=fsclp_pl_dp_1
